* Vector: bound flattening memory, keep over-budget dashes, cheaper edge build (#5195)

- flatten: a path's flattened points are capped at 1 << 20; past it every
  curve keeps a proportional share of its pieces (at least one), so hostile
  handles from files (vmsk, SVG, effect outlines) cannot exhaust memory.
  fill_rasterizer flattens the whole path under one budget.
- stroke: past the dash step budget (or below coordinate precision),
  dash_polyline keeps the dashes made so far and draws the rest solid
  instead of dropping the stroke. Open polylines are no longer copied.
- raster: coordinates are clamped to +-1e15 and edges with a non-finite
  slope (vanishingly short) are skipped, so huge finite coordinates no
  longer produce NaN coverage. fill_rasterizer sorts edges once instead of
  after every component (stable sort, identical order).
- Cleanups: dead miter `half`, dead loop-length check in trace_mask,
  shared mask render body, map_knots helper, shared straight-segment test.

* Vector: bound stroke outline points (#5211)

- stroke_polygons dashes all lines first, then counts round caps and
  joins. When their full-resolution tessellation would exceed 1 << 20
  outline points, every round cap and join gets the same smaller segment
  count (down to 4 per circle, 1 per join; area-exact radius kept).
  Strokes under the budget are unchanged; no piece is dropped.
- The dash step budget (100000) is now shared by all lines of a stroke
  instead of per polyline, so many subpaths cannot multiply the dash
  (and cap) count. Past it the rest is drawn solid, as before.
